When we call a GET.vi for sensors on the Talon FX api, and set the PIDLOOPIDX variable to 0, the return is always zero. Setting the PIDLOOPIDX to 1, we get encoder response.
We are seeing similar behavior in Pheonix Tuner as well. Plots of Velocity from channel 0 show nothing. Plots of Velocity from Channel 1 shows encoder movement.
Anyone else seeing this? Is this a bug or is this supposed to be like this?
It seems to be affecting our Talon FX internal PID. Talon FX is set to factory defaults. Firmware is updated to latest. We are also running example code straight from CTRE github.
